What is compositional.mle?

An MLE package rebuilt around composable solvers, then renamed to match.

compositional.mle performs numerical maximum likelihood estimation in R, with the optimisation strategy expressed as composed pieces rather than configured up front. It began in November 2025 as numerical.mle, a configuration-object package with fixed solvers. The v0.2.0 rewrite replaced that with solver factories sharing a uniform signature and operators for chaining and racing them, and renamed the package accordingly. The two most recent releases are CRAN submission work.

What is Dovetail?

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

compositional.mle vs Dovetail: editorial side-by-side

C0.0

An MLE package rebuilt around composable solvers, then renamed to match.

◆ Current state

compositional.mle performs numerical maximum likelihood estimation in R, with the optimisation strategy expressed as composed pieces rather than configured up front. It began in November 2025 as numerical.mle, a configuration-object package with fixed solvers. The v0.2.0 rewrite replaced that with solver factories sharing a uniform signature and operators for chaining and racing them, and renamed the package accordingly. The two most recent releases are CRAN submission work.

◆ Where it's heading

The arc is a design idea overtaking an implementation: version 0.1.0 exposed configuration functions and named solvers, version 0.2.0 turned solvers into values that can be sequenced with %>>%, raced with %|%, restarted, or conditionally refined, and separated the statistical problem from the optimisation strategy. Since then all effort has gone into CRAN acceptance, dead code removal, policy compliance, validation fixes. That is a package that redesigned itself early and is now trying to get through the door.

◆ Prediction

With the composable API settled, the next work will most likely be additional solvers and transformers plugged into the existing operators rather than another redesign.

5.0

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

◆ Current state

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

◆ Where it's heading

The pattern across the last five releases is access, not capability. Digital Twins went from a two-step workaround — make a generic agent, then change its type — to a first-class create option, then gained a share link that lands a recipient in a conversation rather than a configure page. Chat is being simplified along the same line, with a thinner footer and scoped context that survives the jump to fullscreen. Dovetail is preparing these agents for people who will never build one.

◆ Prediction

Expect the sharing path to keep widening — permissions, guest access, or an embed for a twin link — since a link that opens straight into chat only pays off if it can safely leave the workspace.
